When a guest opens the calendar, available times are automatically displayed in the guest's time zone.
For example, if a guest in New York opens a calendar created by the host in Tokyo time, the available times are displayed in New York time. Dates and times in reminder emails are also automatically converted to the guest's time zone.
For guests using a Mac, the operating system's time zone is used. For guests using Windows or a smartphone, the time zone configured in the browser is used.
